In an experiment, 21 grams of magnesium carbonate were allowed to react with 300 cm3 of a solution of hydrochloric acid containing 2 moles of acid per dm3 of solution. The balanced chemical equation for this reaction is shown below. Calculate the number of moles of hydrochloric acid in 300cm3 of the 2 moles of acid per dm3 of solution used in the experiment.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
